SAMUEL S. POOLE, OF BROOKLINE, MASSACHUSETTS.

CARBURETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 795,233, dated July 18, 1905.

Application filed April '7, 1904. Serial NO- 202,014:-

To all whom it may concern:

Be it known that I, SAMUEL S. POOLE, of Brooklinc, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Carbureting- Machines, of which the following is a specification.

This invention relates to carbureting-machines of the type wherein the delivery of naphtha or other hydrocarbon liquid to the carburetor is dependent upon the operation of the device which delivers air to the carbureter, so that the hydrocarbon liquid and the air are delivered simultaneously and in uni form proportions to the carbureter.

My invention relates more especially to the mechanism for insuring the delivery of the hydrocarbon liquid in quantities which are in uniform proportion to the air passing through the carbureter; and the invention consists in the features of construction and combinations hereinafter described, and referred to in the claims.

In the accompanying drawings, Figure 1 shows a side elevation, partly in section, of a carbureting-machine provided with my improved mechanism for supplying the hydrocarbon liquid to the carburetor. rear elevation of a part of the machine. Fig. 3 is a detail showing a side elevation of the casing within which the devices for measuring the hydrocarbon liquid are mounted, and Fig. 4 is a transverse section through said casing.

In the construction shown in the drawings the air is supplied to the carbureter-coil A by means of an air-pressure device consisting of a hollow cylindrical tank B, nearly filled with water and open at the top, and an airbell C, open at the bottom and adapted to rise and fall within the tank B on the principle of an ordinary gasometer. The interior of the air-bell C is connected with the carbureter-coil A through piping D, within which are located two air-valves (Z d. Then the bell C is raised, the valve d closes, cutting off the communication between the carburetor and the airbell, while the valve (Z opens to Fig. 2 is a The bell O is raised by water under pressure admitted to a cylinder 0, arranged within the tank B and containing a piston c,

which is connected by a rod 0 with the bell C. The admission and exhaust of the water from the cylinder 0 is controlled by a valve mechanism E, constructed and operated like the valve mechanism shown and fully described in the patent to Hinman, No. 7 26,924, of May 5, 1903, to which reference may be had for a full understanding of this valve mechanism.

In general the operation of the valve mechanism is as follows: When the bell C reaches its upper position, the valve mechanism is operated to connect the pipe 0 which leads from the cylinder 0, with the exhaust-pipe e. The bell O now moves down by reason of its weight, forcing the air contained within it through the pipe D and through the carbureter-coil A, the water in the cylinder 0 escaping through the exhaust-pipe e. As the bell C reaches its lower position the valve mechanismE shuts off the communication between the pipe 0 and the exhaust-pipe e and opens the pipe 0 to the water-supply pipe 6. The bell C is then raised by the water admitted into the cylinder 0, thus drawing in a fresh supply of air through the pipe D and valve d. As the air is thus forced through the carbureter-coil A the hydrocarbon liquid is supplied to the upper end of the carbureter coil through a supply-pipe], so that the air as it passes up through the coil mingles with the liquid as it flows down through the coil, producing what is known as an air-gas. This gas is discharged from the upper end of the carbureter-coil into a bell C, similar to the bell C and arranged to rise and fall within a tank B, nearly filled with water. The weight of the bell O causes the gas within the bell to be forced out through a pipe G, which leads to the point where the gas is to be used. A regulating-valve c is connected with the bell O and controls the discharge of gas through the opening A, so that the gas is fed through the pipe G under a uniform pressure. During the time that the air-bell O is being raised to draw in a fresh supply of air the gas stored in the bell C will be fed through the pipe G,

and the bell C will therefore descend within the tank B until the valve mechanism E is operated to allow the bell C to descend. The bell C being somewhat heavier thanv the bell C will then as it descends force the gas through the opening A with suiiicient rapidity to raise the bell. G". hen the bell C has nearly reached its upper position, the valve 0 will partially close the opening A and will govern. the supply of gas admitted through this opening in accordance with. the gas being discharged through the pipe G, so that the pressure under which the gas is fed through the pipe G will be constant.

The mechanism for supplying the hydrocarbon fluid through the pipefin uniform. proportion to the air being forced through the pipe D and carburetor-coil is best shown in Fig. 4. This mechanism consists of an endless series of measuring-buckets F, arranged to travel through a chamber F, to which the hydrocarbon liquid is supplied through a pipe .7- ber F and up a pipef and over a wheel F arranged in. a casing at the uppen end of the pipe] and the pipe f through which the buckets descend to the chamber F. As the buckets pass up over the wheel F they gradually discharge their contents onto a collecting-plate F". This plate is inclined toward its center, so that the liquid deposited thereon flows to the center of the plate and into the pipef, which connects with the plate at this point. The wheel F is operated by the downward movement of the bell C, and consequen tly the amount of liquid deposited upon the plate F" and transferred from said plate to the carbureter through the pipefwill be in uniform proportion to the air forced through the pipe l) and the carbureter by the downward movement of the bell C. The means for connecting the wheel F with the bell C consists of a cord H, passing over a pulley F", secured to the shaft of the wheel F one end of the cord being connected with. a rod H, depending from the bell C, and the other end of the cord being connected with a weight .l'l

As the bell (I descends the rod H. operates the cord ill to turn the wheel F" so that the movement of the wheel is in uniform proportion to the movement of the bell C, thus insuring the delivery of the hydrocarbon liquid in uniform. proportion to the delivery 0 f air to the carlnu'eter. hen the bell C starts upward, the wheel. F is locked against rotation by a ball 72, which wedges between the surface of the pulley F and the inclined surface it, formed on the casing for the wheel F (See Figs. 2 andv 3.) During the upward The buckets F pass through the chammovement of the bell C, therefore, the cord H slips over the pulley F under the influence of the weight H without rotating said pulley or the wheel F Immediately the bell G starts upward, however, the pulley F is rotated by the cord H, since the ball It does not interfere with the movement of the pulley in this direction.

Vfhat I claim, and desire to secure by Letters Patent, is

1. The combination of a carburetor, a series of measuringbuckets for supplying hydrocarbon. liquid thereto, an air-supplying device provided with. a reciprocating member for supplying a measured quantity of air to the carl'mreter, and connections between the series of buckets and reciprocating member for moving the buckets during the airsupplying movement of said member.

2. The combination. of a carburetor, an endless chain of measuring-buckets for delivering hydrocarbon liquid thereto, an air supplying device having a gravitating bell, and connections between said. bell and. said. chain for operating said chain by the downward movement of the boil.

3. The combination of a carburetor, a vertically-moving chain of buckets for supplying hydrocarbon liquid through which the chain passes during the lower part of its travel, a receiving-plate upon which the liquid is discharged, a conduit therefrom to the carbureter, an air-supplying bell for delivering a measured quantity of air to the carbuireter, and direct coimcctions between the bell and chain of buckets for moving the buckets in unison with. the air-supplying movement of the bell.

at. The combination of a carburetor, a series of measuring-buckets for supplying hydrocarbon liquid to the carlnireter, an airbell for supplying a measured quantity of air to the carburetor, and devices for directly connecting the bell with the series of buckets to move the buckets in unison with the airsup ')lying movement of the bell.

5. The combination of a carlmreter, a measuring device for delivering hydrocarbon liq uid thereto, an air-simplying device having a gravitating bell, and connectirms between. said bell and. said measuring device for directly operating said device by the downward movement of the bell.
